/**
|
|
* Multiply two matrices element wise. The function accepts both matrices and
|
|
* scalar values.
|
|
*
|
|
* Syntax:
|
|
*
|
|
* math.dotMultiply(x, y)
|
|
*
|
|
* Examples:
|
|
*
|
|
* math.dotMultiply(2, 4) // returns 8
|
|
*
|
|
* a = [[9, 5], [6, 1]]
|
|
* b = [[3, 2], [5, 2]]
|
|
*
|
|
* math.dotMultiply(a, b) // returns [[27, 10], [30, 2]]
|
|
* math.multiply(a, b) // returns [[52, 28], [23, 14]]
|
|
*
|
|
* See also:
|
|
*
|
|
* multiply, divide, dotDivide
|
|
*
|
|
* @param {number | BigNumber | Fraction | Complex | Unit | Array | Matrix} x Left hand value
|
|
* @param {number | BigNumber | Fraction | Complex | Unit | Array | Matrix} y Right hand value
|
|
* @return {number | BigNumber | Fraction | Complex | Unit | Array | Matrix} Multiplication of `x` and `y`
